MASH/LAUTER/GRIST/BOIL NOTES:
Grist: Used Pilsner instead of 2 row due to a shortage of 2 row malt. Malt has the same diastic power, it shouldn't be perceptible in the change of the flavor in an IPA.
Mash: Starting temp a little low.
Boil: a lot of hot break and 3 near boil overs. Pilsner issue?
FERMENTATION NOTES:
Yeast from second yeast washing. Aggressive Krausen development in starter and fermenter. Change due to Fermaid K?
